HEATER

2002 GMC Acadia • 6 cylinder 2WD Automatic • 250,000 miles

I have a 2002 gmc safari van and the heater is blowing cold air, the blower motor is working but no heat. I changed the thermosat, the van comes up to temperature but still no heat. Heater core fine, is there a bleeder valve somewhere that is should be looking for?
